Expanding Cloud Native Capabilities with WASM: A Case Study of Harbor

Explore how WebAssembly (WASM) can extend cloud-native capabilities in this 39-minute conference talk from the Cloud Native Computing Foundation (CNCF). Dive into a case study of Harbor, a cloud-native artifact registry, and learn how WASM integration enables non-invasive and flexible extension of business applications without modifying original code. Discover the parallels between Harbor and the Linux kernel, and WASM and user-provided eBPF programs. Examine how Harbor provides mounting points for various events, such as pre-pull requests, allowing users to filter requests with custom WASM programs. Gain insights into implementing fine-grained permission control and artifact security auditing before users pull artifacts. Presented in both English and Chinese, this talk offers valuable knowledge for cloud-native practitioners looking to enhance their understanding of WASM's potential in expanding cloud-native functionalities.
